We look at the division of 921200 by 5 
The aim is to understand the frequency of 5 in 921200.

Advancing to step 1:
When dividing 9 by 5, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 5 from 9 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 5

Step 2:
5 can be fit into 42 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 40 from 42 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 5

Going ahead to step 3:
If we divide 21 by 5, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 184.0
Deduct 20 from 21 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 5

On to step 4:
5 can be fit into 12 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 1842.0
Deduct 10 from 12 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 5

Moving on to step 5:
5 can be fit into 20 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 18424.0
If we take 20 away from 20, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 5

Let's proceed to step 6:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 184240.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 184240.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 184240.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 184240.0 and a remainder of 0.0.
